Incompatibility with updated OS and software versions

[shawnferry]

For various reasons notably including a desire to easily use an NVME drive we are targeting the Raspberry Pi 5 in our testing.

We are trying to use:

• rpi5
• python 3.11
• Ubuntu 24.04 (23.10 until release)

Installed via the 1.2.2 deb with modified dts and locally compiled python3.9 loading fail with: *** SystemError: Failed to initialize libwlmio

For RPI5

[64762.230168] OF: resolver: node label 'uart5' not found in live devicetree symbols table
[64762.238187] OF: resolver: overlay phandle fixup failed: -22

I've tried a naive change in wlmio.dts but I'm unable to cleanly build/package a test release. Pointing uart5 -> 4 and uart3 -> 2

Post change dtoverlay emits the following on load

For Ubuntu/Debian/Pi OS

/boot has been moved to /boot/firmware

Package building fails with

dh_usrlocal: error: debian/libwlmio/usr/local/lib/python3.11/dist-packages/_wlmio.cpython-311-aarch64-linux-gnu.so is not a directory
make: *** [debian/rules:3: binary] Error 25

As a fallback I will try with Ubuntu 22.04

My in process changes here #3

We don't currently support Ubuntu but they may change in the near future. We definitely want to fix the problem with the overlay but we'll have to source a Pi 5 for testing. I'll get back to you.

I have a Pi 5 in my hands and am working through the various compatibility problems now.
